Protein Crystallography Products & Reviews

Protein crystallization is the process of crystallizing purified proteins for 3D structure analysis by x-ray crystallography. The main methods of protein crystallization include sitting drop, hanging drop and microbatch. It is important to control parameters such as pH, temperature and concentration. Following crystallization, detectors and software are used for data collection and analysis.

Trypsin/Lys-C Mix, Mass Spec Grade

Promega Corp.

Trypsin/Lys-C Mix, Mass Spec Grade, is a mixture of Trypsin Gold, Mass Spectrometry Grade, and rLys-C, Mass Spec Grade. The Trypsin/Lys-C Mix is designed to improve digestion of proteins or protein mixtures in solution.   Using the conventional trypsin digestion protocol (i.e., overnight incubation at nondenaturing conditions), Trypsin/Lys-C Mix improves protein digestion by eliminating the majority of missed cleavages,…

Sequencing Grade Modified Trypsin

Promega Corp.

Trypsin is a serine protease that specifically cleaves at the carboxylic side of lysine and arginine residues.   The stringent specificity of trypsin is essential for protein identification. Native trypsin is subject to autolysis, generating pseudotrypsin, which exhibits a broadened specificity including a chymotrypsin-like activity. Such autolysis products, present in a trypsin preparation, would result in addition…

PCT™ Pre-Crystallization Test

Hampton Research

The PCT Pre-Crystallization Test is used to determine the appropriate protein concentration for crystallization screening. Sample concentration is a significant crystallization variable. Samples too concentrated can result in amorphous precipitate, while samples too dilute can result in clear drops. Precipitate and clear drops are typical crystallization screen results for reagent conditions which do not promote crystallizati…
